Blundellsands Ward Labour Councillor Veronica Bennett has been working on getting to the bottom of the steady deterioration of the road surface on Holden Road in Brighton-le-Sands.
The centre of the road has deteriorated so much that mini lakes are forming along the length of the centre of the road.
Cllr Bennett said: "I have received a number of complaints about Holden Road in Brighton-le-Sands. I am told by constituents that, following work carried out on the pipes beneath the road the middle of the road surface began to dip along the length of the road.
"This has become more pronounced in recent years and there is now a very clear ‘spine’ along the centre of the road. It is causing problems for car suspensions and also presents flooding problems as the dips are big enough to collect a significant amount of water during wet weather which cannot drain.
"The residents are really not happy with this ongoing situation and both they and I want action taken to fix the problem."
Cllr Bennett secured an inspection of the road to find out what is causing the problem, before repair works can begin.
Cllr Bennett said: "Despite initial information which indicated that United Utilities may be responsible due to the open cut sewer works a few years back, United utilities now deny that they carried out such work on the road. So engineers are again going out to the road to ascertain what the cause of the problem is.
"Once these inspections have been competed, I will be calling for all of the necessary repairs to be made, which should then ensure that this doesn't happen again."
Crosby and Blundellsands Labour Action Team member Ben Murphy said he was pleased the residents would finally see improvements to the road.
Ben said: "The condition of Holden Road has come up a number of times now and each time we have raised it with the relevant bodies. So I am obviously really pleased that Sefton Council is taking the lead and carrying out inspections to find out just what needs to be done to end the problem before resurfacing the affected areas.
"Residents told us that the indents in the road had been damaging their cars, but I also have concerns that as the temperature gets colder, the water which has gathered in the middle of the road will turn to ice making the road treacherous to drive or even walk on.
"So we are pleased action is being taken and we will make sure throughout the process that residents in and around Holden Road are kept fully informed."
